Warner Brothers released the first trailer for the upcoming film SHAZAM! which stars Zacharey Levi and will be released on April 5, 2019. The trailer shows the origins of Shazam and truly does resemble the movie Big but with superpowers.
Warner Brothers also showed a little footage of Wonder Woman, but that was a SDCC exclusive. Description of the video shown will be added to the Highlights article at the end of the day, but basically it was her saving a bunch of kids in a mall.
